' BRUSH ATTACHMENT.

SPECIFICATION forming part of Letters VPatent No. 761,522, dated May 31 1904.

Application filed May 12, 1903. Serial No. 156,786.. (No model.)

-To a/ZZ whom it may cori/cern: Be it known that I, GEORGE MIELENHAUSEN, a cltizen of the United States of America, and

ya resident ofv New York, in the county and handle under any desired angle thereto. This is desirable when sweeping, cleansing, or washing the floor near the wall or in the corners.

Heretoi'ore attachments have been used which were provided with devices constructed so that the brush had to be lifted up from the iioor and the attachment then operated by hand in order to obtain a change in the angular position of the handle to the stock or block of the brush. l

My improved attachment 'pertains to that type of brush attachments which enable the operator to obtain any angular change in the position of the brush to the handle without `lifting up the brush by a simple operation while the brush is on the floor.

The invention is illustrated in the accompa- -nying drawings, in which- I block or stock by means of screws s, as is seeny in Fig. 2. At the top of the attachment there is provided a f holder 7b for the brush handle or stick.

The attachment comprises a heavy metal plate c, 'preferably circularin form, having a central opening 0. About halfl of the thickness of the lower inner portion c is taken out and the remaining half provided with indentations c2, arranged circularly, as shown in Fig. il. The plate c is further provided with a number of openings o3 for the screws s, by -meansof which the attachment is secured to the brush. l y

The central part Z of the attachment, as shown in Figs. land 2, consists of a tubular portion (Z, which is hollow. The top Z2 of the tubular portion CZ is solid and extends into a conical holder 7L, which is adapted to receive the brush handle or stick e. The tu- 'bular part d tits loosely in the opening 0 of4 the plate c. At the bottom end ,of the tubular portion d' there is a flange f, which is provided with little knobs k. The flangef contains the same number of knobs as there are indentations in the plate aand lits loosely in the remaining halt1 of the lower inner portion c', which has the indentations o2. The knobs and indentations are so arranged that they coincide and register. The thickness oi' the iiange f is so selected that it appears to be countersunk when the knobs of same regp ister in the indentations of the plate c, thus permitting of a slight movement. Within the hollow space of the tubular portion 0l' a spring g is inserted, las is seen in Fig. 2.' Thereis further a bottom plate t' of metal and of same shape as the top plate c. This plate is provided with openingsZ of like number as there are openings 03 in the plate c.

When mounting the attachment, the plate I-is iirst placed 4on the top of the stock ofthe brush, and then the plate c, the central part al', and the spring g are assembled and placed thereon so that the openings c3 and Zcoincide. The screws s are now passed through same, thus securing the attachment to the brush and at the same time compressing the spring g. Assuming now that the brush is ready for use and the handle in its usual position thereto, as shown in Fig. 1, thenthe' spring g will keep the knobs and the indentations 02 together, thus maintaining theusual position of the handle to the brush, and the same may be used like any ordinary brush. If it is TOO now desired to make a change in the angular position of the brush to the handle, then, as is plainly seen, the force of the spring must be overcome by the operator. This is easily effected because the central part d and its tlange f fit loosely in the opening 0 oi' the plate c and can therefore be moved sidcward and downward. If the operator now forces the central part slightly downward by means of the handle without raising the brush, then the knobs la are disengaged from the indentations c2. A sideward movement will now change the position of the knobs, and upon release the knobs will register in other indentations, thereby changing the angular position of the brush to the handle. As the knobs and indentations are circularly arranged, the described operation may be repeated until the brush has described a complete circle around the handle. By means of this operation the brush may be `continuously turned without adjusting any parts of the attachment.

The knobs and indentations operating as dedescribed form a lock, retaining the active parts of the device in their position until the operator disengages them and locks them again in the changed position by releasing the spring.

From the Jforegoing it will be observed that the construction described provides what may be properly termed a yieldinglylocked swivel for the brush-handle to provide for normally holding the latter in iixed relation to the brush back or body, while at the same time permitting the operator to disengage the locking means and shift the handle to a different angular position, in which latter position it is relocked by the same locking means. By reason oi' this operation the plate c of the attachment constitutes a lixed bearing member or plate, whose inner cut-off portion forms a clearance-chamber to accommodate the vertical play of the rotatable member (l and which is formed at the top with the inturned holding-flange c. This inturned holding-liange carries the aforesaid indentations, forming retaining-recesses to receive the complemental locking projections or knobs Z2, carried on the outturned engaging liange at the lower end of the tubular part of the rotatable swivel member d.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- In a swivel -attachment for brushes, the combination, of a stationary bearing-plate lixedly attached to a flat brush-back and provided above the plane of the back with a eentral clearance-chamber and an inturned annular holding-flange overhanging said chamber and provided atits inner face with a circular series of retaining-recesses, a rotatable swivel member comprising an integral body embodying a rigid obliquely-disposed socket for the handle, and a tubular or hollow portion extending through and above the circular opening within said holding-flange and provided at its lower end with an outturned circular engaging liange underlapping said holdingflange and provided on its upper face with a circular series of locking projections designed to register with said retaining-recesses, and a spring housed wholly within the tubular or hollow part of the swivel member and adapted to bear at one end against the brush-back to provide for yieldingly holding the parts interlocked.
